Definitions
- This invention relates to an edge trim for fitting to a flange around a door or door opening on a motor vehicle and to a method of fitting the edge trim.
- the invention is also applicable to weatherstrips mounted on or integral with such edge trims.
- Edge trims for use in the motor industry are normally extruded from a synthetic resinous material and incorporate a metallic carrier therein, the carrier being of slotted metal construction or knitted zig-zag wire construction so as to impart rigidity and resilience to the edge trim.
- a pile or elastomeric seal is extruded with or attached to the edge trim.
- the edge trim either with or without a weatherstrip is supplied to the motor vehicle manufacturer in long reeled lengths ready for application to a flange around the door or boot or frame of the door or boot of a vehicle in a state ready to be fitted to the flange, i.e. such that it has a generally U-shaped cross-section, the internal configuration of the U being such that the edge trim can be applied to the flange relatively easily either manually or with a machine and will not subsequently become displaced from the flange.
- the thickness of the metal carrier can vary slightly as can the thickness of the elastomeric material of the extrusion of the dimensions of any gripper fins provided on the inner surfaces of the U-shape.
- the flange to which the edge trim is fitted can have a thickness made up of one, two, or even more layers of sheet metal welded together with spot welds which themselves can change the thickness of the flange.
- edge trim is pre-formed into its U-shape to accommodate all these different thicknesses, it is likely to be slightly too wide for single layer thicknesses and slightly too narrow for three or more layer thicknesses and as a result, the edge trim may not form a satisfactory grip where the flange is of one layer thickness, and where the flange is of more than two layer thickness it may be extremely difficult for the fitter or machine to apply the edge trim to the flange and as a result the edge trim is abused during fitting and does not perform satisfactorily in use.
- a water-tight seal is not always achieved when the trim is fitted onto the flange because channels are formed between the stepped layers and the trim, along which water can travel.
- a fitter sometimes applies a mastic to either the flange or the trim before fitting one to the other. The mastic seals the channels. This "pre-treating" step is time consuming and expensive and makes the trim almost impossible to remove subsequently.
- the trim has one or series of gripper fins located within the U-shaped.
- the gripper fins allow the edge trim to be applied easily to a flange but hinder the displacement of a trim off the flange once the trim has been fitted onto the flange. This aspect is known as increasing the "pull-off" value.
- EP-A-0317086 discloses some trims that overcome the problems associated with the edge trims that are normally used in the motor industry. These trims take advantage of the ever increasing use of robotics in the manufacture of motor vehicles.
- European patent application No. 88309905.3 discloses a generally U-shaped edge trim having a series of traditional gripper fins. The arms of the U-shaped edge trim being inclined at an angle of about 45° to each other. This is known as an open configuration. When the edge trim is applied to a flange it can subsequently be crimped or otherwise deformed into closed gripping engagement with the flange.
- the "push-on” values of the trims are very low. Moreover, once the edge trim has been crimped onto a flange, the "pull-off" value is extremely high.
- trims that include gripper fins e.g. the known edge trims and the edge trims of European patent application No. 88309905.3
- gripper fins e.g. the known edge trims and the edge trims of European patent application No. 88309905.3
- the present invention has been conceived not only to overcome the problems associated with the known edge trims but also to do away with the need for gripper fins and use any alternative gripping material which cannot be used with traditional U-shaped edge trims because it has too high a push-on value, i.e. it is impossible to fit the edge trim to a flange. It is known that there is a relationship between push-on and pull-off values, i.e. the higher the push-on value the higher the pull-off value, but for a very high pull-off value which is what the motor industry requires, the push-on value is too great to get the traditional edge trim, regardless of gripper fin design, onto the flange.
- the edge trim of this invention overcomes this problem.
- the present invention also obviates the need for a fitter to conduct a "pre-treating" step of applying a mastic to either a flange or a trim.
- an edge trim for application to a flange such as is found on the edge of a door or around a door opening in a motor vehicle, comprising a strip defining a channel, and a carrier incorporated at least partly within the strip characterised in that a sponge or foam-like material is secured within the channel, such that at least part of a flange can be located within the channel and the edge trim can subsequently be crimped or otherwise deformed into gripping arrangement with the flange.
- the carrier may be made of metal. Also, the strip may completely enclose the carrier. In a preferred embodiment, the carrier has indentations pointing towards the channel.
- the strip is formed of an extruded synthetic resinous material.
- the trim may further comprise a fin along each edge of the channel that is dimensioned to retain the sponge or foam-like material within the channel.
- the channel has a generally U-shaped cross-sectional shape but with the arms of the U-shape not being parallel but diverging from the base of the U.
- the arms are inclined to each other at an angle between 10° to 90°; advantageously at an angle of 45°.
- the sponge or foam-like material can be a hot melt foam material or it can be an EPDM sponge.
- the method further includes the step of sensing the thickness of the flange and applying a deforming step on the edge trim so that the edge trim will grip the flange uniformly throughout its length regardless of the thickness of the flange.
- a predetermined crimping force is applied to the edge trim to deform it into its second condition, regardless of the thickness of the flange.
- edge trim can be deformed by means of a robot.
- crimping means such as a plurality of crimping rollers, supported on a robot arm.
- the present invention therefore provides an edge trim that is easy and cheap to manufacture and one that is also easy to secure to a flange around a door opening or on a door or the like, and which is difficult to remove from the flange
- each edge trim 1 has a metallic carrier 3 e.g. of zig-zag wire or slotted or stamped metal incorporated within a strip 5.
- the metallic carrier 3 is shown in simplified form in the drawings.
- the strip 5 is extruded from a known thermoplastic or thermosetting resinous material, such as polyethylene.
- the strip 5 is of open U-shaped form and defines a channel 11 having walls or arms 7a, 7b.

Abstract
Description
- This invention relates to an edge trim for fitting to a flange around a door or door opening on a motor vehicle and to a method of fitting the edge trim. The invention is also applicable to weatherstrips mounted on or integral with such edge trims.
- Edge trims for use in the motor industry are normally extruded from a synthetic resinous material and incorporate a metallic carrier therein, the carrier being of slotted metal construction or knitted zig-zag wire construction so as to impart rigidity and resilience to the edge trim. Very often, a pile or elastomeric seal is extruded with or attached to the edge trim. Normally, the edge trim either with or without a weatherstrip is supplied to the motor vehicle manufacturer in long reeled lengths ready for application to a flange around the door or boot or frame of the door or boot of a vehicle in a state ready to be fitted to the flange, i.e. such that it has a generally U-shaped cross-section, the internal configuration of the U being such that the edge trim can be applied to the flange relatively easily either manually or with a machine and will not subsequently become displaced from the flange.
- There has always been a problem with the fitting of such U-shaped edge trims whether or not they incorporate a weatherstrip because of the manufacturing tolerances both of the edge trim and the motor vehicle itself. For example, the thickness of the metal carrier can vary slightly as can the thickness of the elastomeric material of the extrusion of the dimensions of any gripper fins provided on the inner surfaces of the U-shape. Furthermore, the flange to which the edge trim is fitted can have a thickness made up of one, two, or even more layers of sheet metal welded together with spot welds which themselves can change the thickness of the flange.
- In practice, therefore, it is difficult for a fitter or a machine to apply a U-shaped edge trim to a flange in such a way that it will remain on the flange during the life of the vehicle. The problem of course is that for a single layer thickness of metal sheet, the internal dimensions of the U-shaped edge trim need to be considerably less than for that portion of the flange which is made up of say three layers of metal sheet. If the edge trim is pre-formed into its U-shape to accommodate all these different thicknesses, it is likely to be slightly too wide for single layer thicknesses and slightly too narrow for three or more layer thicknesses and as a result, the edge trim may not form a satisfactory grip where the flange is of one layer thickness, and where the flange is of more than two layer thickness it may be extremely difficult for the fitter or machine to apply the edge trim to the flange and as a result the edge trim is abused during fitting and does not perform satisfactorily in use.
- For example, a water-tight seal is not always achieved when the trim is fitted onto the flange because channels are formed between the stepped layers and the trim, along which water can travel. In order to overcome this problem, a fitter sometimes applies a mastic to either the flange or the trim before fitting one to the other. The mastic seals the channels. This "pre-treating" step is time consuming and expensive and makes the trim almost impossible to remove subsequently.
- If a known edge trim is to be retained securely on a flange, it is advisable that the trim has one or series of gripper fins located within the U-shaped. The gripper fins allow the edge trim to be applied easily to a flange but hinder the displacement of a trim off the flange once the trim has been fitted onto the flange. This aspect is known as increasing the "pull-off" value.
- However, apart from the aforementioned problems, further problems are associated with the known edge trims. Often a large force is required to fit the trim onto the flange because the flange has to deform the gripper fins (i.e. the trims have a large "push-on" value).
- European patent application No. 88309905.3 (published as EP-A-0317086) discloses some trims that overcome the problems associated with the edge trims that are normally used in the motor industry. These trims take advantage of the ever increasing use of robotics in the manufacture of motor vehicles.
- In particular European patent application No. 88309905.3 discloses a generally U-shaped edge trim having a series of traditional gripper fins. The arms of the U-shaped edge trim being inclined at an angle of about 45° to each other. This is known as an open configuration. When the edge trim is applied to a flange it can subsequently be crimped or otherwise deformed into closed gripping engagement with the flange.
- By using the open-arm configuration, the "push-on" values of the trims are very low. Moreover, once the edge trim has been crimped onto a flange, the "pull-off" value is extremely high.
- However, it is an accepted fact that the manufacture of trims that include gripper fins (e.g. the known edge trims and the edge trims of European patent application No. 88309905.3) can be expensive. This is because the trims have to be extruded from complicated dies.
- The present invention has been conceived not only to overcome the problems associated with the known edge trims but also to do away with the need for gripper fins and use any alternative gripping material which cannot be used with traditional U-shaped edge trims because it has too high a push-on value, i.e. it is impossible to fit the edge trim to a flange. It is known that there is a relationship between push-on and pull-off values, i.e. the higher the push-on value the higher the pull-off value, but for a very high pull-off value which is what the motor industry requires, the push-on value is too great to get the traditional edge trim, regardless of gripper fin design, onto the flange. The edge trim of this invention overcomes this problem. The present invention also obviates the need for a fitter to conduct a "pre-treating" step of applying a mastic to either a flange or a trim.
- According to the present invention, we provide an edge trim for application to a flange such as is found on the edge of a door or around a door opening in a motor vehicle, comprising a strip defining a channel, and a carrier incorporated at least partly within the strip characterised in that a sponge or foam-like material is secured within the channel, such that at least part of a flange can be located within the channel and the edge trim can subsequently be crimped or otherwise deformed into gripping arrangement with the flange.
- The carrier may be made of metal. Also, the strip may completely enclose the carrier. In a preferred embodiment, the carrier has indentations pointing towards the channel.
- Preferably the strip is formed of an extruded synthetic resinous material.
- The trim may further comprise a fin along each edge of the channel that is dimensioned to retain the sponge or foam-like material within the channel.
- Preferably, the channel has a generally U-shaped cross-sectional shape but with the arms of the U-shape not being parallel but diverging from the base of the U. Typically, the arms are inclined to each other at an angle between 10° to 90°; advantageously at an angle of 45°.
- The sponge or foam-like material can be a hot melt foam material or it can be an EPDM sponge.
- According to the present invention, we also provide a method of fitting an edge trim as described above to a flange, such as is found on the edge of a door or around a door opening in a motor vehicle, comprising the steps of forming the channel of the edge trim into a first, opened out condition, presenting the channel of the edge trim in this first condition to the flange, until the channel loosely engages the flange and subsequently deforming the edge trim into a second closed condition in which it grips the flange.
- Preferably, the method further includes the step of sensing the thickness of the flange and applying a deforming step on the edge trim so that the edge trim will grip the flange uniformly throughout its length regardless of the thickness of the flange.
- Advantageously, a predetermined crimping force is applied to the edge trim to deform it into its second condition, regardless of the thickness of the flange.
- Furthermore, the edge trim can be deformed by means of a robot. For example, crimping means, such as a plurality of crimping rollers, supported on a robot arm.
- The present invention therefore provides an edge trim that is easy and cheap to manufacture and one that is also easy to secure to a flange around a door opening or on a door or the like, and which is difficult to remove from the flange
- The invention is now described by way of example with reference to the accompanying drawings in which:―
- Figure 1 is a sectional view of one edge trim according to the present invention,
- Figure 2 is a sectional view of a second edge trim according to the present invention,
- Figure 3 is a sectional view of the second edge trim when crimped on one type of flange,
- Figure 4 is a sectional view of a third edge trim according to the present invention,
- Figure 5 is a sectional view of the second edge trim when about to crimped on a second type of flange, and
- Figure 6 shows the edge trim of any one of figures 1-5 being applied to a flange and subsequently being deformed into gripping engagement therewith with the aid of a robot arm.
- Referring to the drawings, each
edge trim 1 has ametallic carrier 3 e.g. of zig-zag wire or slotted or stamped metal incorporated within astrip 5. Themetallic carrier 3 is shown in simplified form in the drawings. Thestrip 5 is extruded from a known thermoplastic or thermosetting resinous material, such as polyethylene. Thestrip 5 is of open U-shaped form and defines achannel 11 having walls orarms - A sponge or foam-like material 9 (such as EPDM sponge or a hot-melt foam) is secured to the
channel walls strip 5, or combined with the strip in a separate operation. The sponge of foam-like material 9 is retained within thechannel 11 by means offins 19 which extend along eacharm - The channel walls are inclined to each other at an angle of approximately 45°. When the walls are in this first open condition, the trim can receive at least part of a flange, such as the
flange 13 shown in Figure 3. Theflange 13 comprises two layers of metal welded together. Anothertypical flange 15 is shown in Figure 5.Flange 15 comprises two layers of metal having an up-turnededge portion 17. - To secure an edge trim according to the present invention to a flange, the
edge trim 1 while in the open position is first placed over the flange such as in Figure 5. Thestrip 5 is then crimped or deformed so that thematerial 9 closes in around theflange 13, so that theflange 13 is held secure within the confines of the material 9 (such as shown in Figure 3). When the trim is crimped onto the flange a large amount of force is needed to remove the trim from the flange (i.e. the flange has a high pull-off value). The trim is held in place by means of thecarrier 3. - It is clear from the above description that, because the
material 9 is compressible, thestrip 5 can be ′overbent′ to increase the pull-off value. - The pull-off value can be increased in several other ways. For example, the
carrier 3 can be provided with one ormore indentations 21 that point towards thechannel walls carrier 3 is concentrated at theindentations 21. (see figure 2 or figure 4). - Alternatively, the
carrier 3 can be provided with asingle indentation 23 that is adapted to fit under an up-turnededge 17 of a flange, such asflange 15, when the trim is crimped onto the flange. In other words, theindentation 23 and theedge 17 lock together, as shown in figure 5. - In all of the above constructions, the
strip 5 can be provided withfins 19 at the ends of thechannel walls Fins 19 not only prevent the displacement of the sponge/foam material 9 from within the confines of the trim, while the trim is being crimped onto a flange, but also provide a moisture seal to prevent rusting of the flange. - The trim according to the present invention has been specially designed to take advantage of the ever increasing use of robotics in the manufacture of motor vehicle. In this regard, the trim can be fitted to vehicle flange by means of a suitable robotic apparatus, such as that shown in Figure 6.
- The apparatus shown in Figure 6 includes a
robot arm 31, on which a closing assembly 33 is mounted, the closing assembly incorporating two pairs of bevelled crimpingrollers 35, at least oneguide roller 36 and atensioning roller 37, and some form of sensing device (not shown) to ensure that the crimping rollers deform thechannel walls - It will of course be appreciated that the edge trim could have many other constructions from these illustrated; for example, it can have a weatherstrip or seal attached to or integral therewith. Instead of having an extruded synthetic, resinuous body, the body could be formed of textile material wrapped around a carrier. Many other constructions are possible.
- Figures 1, 2 and 4 show the
channel walls - It is even envisaged that the edge trim could be supplied to the motor manufacturer in flat form and the manufacturer could then either apply the edge trim to the flange and crimp it up to the construction shown in Figure 3 in a single operation or initially deform the edge trim to a condition similar to that shown in Figures 1, 2 and 4 and then apply it to the flange and subsequently deform it again to the condition shown in Figure 3.
- It will also be appreciated that the method and apparatus for deforming the edge trim illustrated in figure 6 is only one example of many different methods and apparatus which could be used.
- It will of course be appreciated that while the present invention has been specifically conceived for edge trims for use in the motor industry, it could be used for edge trims having other uses.
- The advantage of the present invention is that it solves a problem which motor manufacturers in particular have suffered from for many years, namely, the satisfactory fitting of an edge trim or weatherstrip on to a flange of variable thickness on a vehicle. In particular, the trim must be easy to fit, but difficult to remove. This is possible with the trims described above. Furthermore, it is possible to ensure that the trim, with or without weatherstrip, can be fitted with a uniform grip on a flange regardless of the dimensions of the flange and without the need for gripper fins.
- It will of course be understood that the present invention has been described above purely by way of example, and modifications of detail can be made within the scope of the invention.
